The linked github repository doesn't break out whatever the fix is to the rtsx_pci driver is. Therefore it is all but impossible to figure out what was changed.
Another user reported this today with 5.0.0-27-generic where 64GB cards are readable but 256GB cards are not. It isn't clear if the power- signalling errors are critical or incidental: Sep 15 11:55:59 kubuntu-laptop kernel: mmc0: cannot verify signal voltage switch Sep 15 11:56:00 kubuntu-laptop kernel: mmc0: new ultra high speed SDR104 SDXC card at address 0001 Sep 15 11:56:00 kubuntu-laptop kernel: mmcblk0: mmc0:0001 GC2QT 59.6 GiB Sep 15 11:56:00 kubuntu-laptop kernel: mmcblk0: p1 Sep 15 11:57:06 kubuntu-laptop kernel: mmc0: card 0001 removed Sep 15 11:57:14 kubuntu-laptop kernel: mmc0: cannot verify signal voltage switch Sep 15 11:57:14 kubuntu-laptop kernel: mmc0: tuning execution failed: -22 Sep 15 11:57:14 kubuntu-laptop kernel: mmc0: error -22 whilst initialising SD card Sep 15 11:57:15 kubuntu-laptop kernel: mmc0: error -110 whilst initialising SD card Sep 15 11:57:17 kubuntu-laptop kernel: mmc0: cannot verify signal voltage switch Sep 15 11:57:17 kubuntu-laptop kernel: mmc0: tuning execution failed: -22 Sep 15 11:57:17 kubuntu-laptop kernel: mmc0: error -22 whilst initialising SD card Sep 15 11:58:08 kubuntu-laptop kernel: mmc0: cannot verify signal voltage switch Sep 15 11:58:08 kubuntu-laptop kernel: mmc0: new ultra high speed SDR104 SDXC card at address 0001 Sep 15 11:58:08 kubuntu-laptop kernel: mmcblk0: mmc0:0001 GC2QT 59.6 GiB Sep 15 11:58:08 kubuntu-laptop kernel: mmcblk0: p1 Sep 15 11:58:46 kubuntu-laptop kernel: mmc0: card 0001 removed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1735099 Title: Realtek Card Reader not working (kernel driver) Status in linux package in Ubuntu: Triaged Bug description: This is the situation if I use the normal 4.13 kernel driver [ 1899.245301] mmc0: cannot verify signal voltage switch [ 1899.377540] mmc0: new ultra high speed SDR104 SDXC card at address e624 [ 1899.401829] mmcblk0: mmc0:e624 AGGCE 59.5 GiB [ 1899.404700] mmcblk0: p1 [ 1899.620084] mmcblk0: error -110 sending status command, retrying [ 1899.620231] mmcblk0: error -22 sending status command, retrying [ 1899.620419] mmcblk0: error -22 sending status command, aborting [ 1899.905535] mmc0: cannot verify signal voltage switch [ 1900.136253] mmcblk0: error -22 sending status command, retrying [ 1900.136396] mmcblk0: error -22 sending status command, retrying [ 1900.240070] mmcblk0: error -110 sending status command, aborting [ 1900.240084] print_req_error: I/O error, dev mmcblk0, sector 8 but it works perfectly if I use the patched driver on kernel 4.4-4.7 this one https://github.com/Zibri/Realtek-rts5229-for-4.4-kernel the problem is that I can't compile it on 4.13 and anyway this affects a lot of systems using 5229/5227 many laptops use this. any solution??
